Therapy of kidney diseases in poor people in France during the 18th century.

The idea of using simple and easily available remedies to treat different diseases is typical of ancient medicine and one of the first examples can be found in Galen's works. This type of Medicine was called "Medicine for the poor" in the 18th century. This expression refers to the use of simple substances, available in nature, like plants, herbs, flowers, fruit, minerals etc, to treat some of the more common diseases. Evidence of this tendency in the early 18th centry is a textbook of Medicine written in France by Dubé in 1669. This work has been reprinted several times, and translated from French into English in 1704 and into Italian in 1715 by Sebastiano Castellini. In his work Dubè describes the therapeutic remedies made with natural substances. Some of these substances were used to treat renal diseases, in particular nephrolithiasis, kidney and bladder inflammatory disease, renal ulcer, dysuria and incontinence.
